Title: Improvements in or relating to machines for trimming shoe parts
IPC: A43D27/00
Filed: 1935-08-17
Abstract: 461,812. Boot making machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and BARKER, W.A. (United Shoe Machinery Company Soc. Anon. Belge (partly)) Aug. 17, 1935, Nos. 23144 and 34013. [Class 17 (i)] Trimming.-A machine for trimming a lower marginal portion of the upper of a lasted shoe, particularly the margin of an out-turned upper projecting beyond the sole edge, of the kind comprising a horizontally-reciprocating knife with an inclined cutting edge co-operating with a shearing edge on a work-support which engages the work adjacent the angle between the side of the upper and its outturned margin, is provided with a member which is adapted to support the said margin, against the thrust of the knife, above the level of said shearing edge, and to move aside as the knife advances in its cutting stroke. As shown, Figs. 1 and 2, the knife 5 carried by a reciprocating rod 3 co-operates with the shearing edge of the horizontal part 19 of the vertically-adjustable, hook-shaped, worksupport 15. The shearing edge is positioned in the plane of the lower surface of a sole edge gauge 25. The additional member 37, which supports the margin of the upper extending beyond the sole edge, is pivoted in a slot in a bracket 41, and is biassed by a spring 49 so that its lower surface engages the upper surface of the portion 19 of the work-support 15. The said lower surface is inclined to the left, to co-operate with the wedge-shaped cutting extremity of the knife. Consequently, the member 37 is rocked about its pivot 39 by the advancing knife, so that no gap is formed between the engaging surfaces of the knife and member, and the margin of the upper to be removed is supported adequately during the cutting operation. In a modification, Fig. 4, the support member 137 is arranged to oscillate substantially in a plane perpendicular to the direction of movement of the knife. It is carried by a bell-crank lever 139, 141 which is rocked by connections to the operating rod 3 of the knife 105. The extent of oscillation is adjustable, so that an inclined lower surface 173 on the member 137 always co-operates with the wedge-shaped extremity 111 of the knife. A spring-plunger, not shown, is arranged to press the member 137 downwardly against the knife 105 and the shearing edge 121 of the lower work-support 19. The work-engaging face of the latter is inclined forwardly, to improve the support of the upper where a rand has been secured around the out-turned flange.

The knife-bar 3 is driven continuously by a belt 20 transmitting motion from a pulley on the engine shaft to a pulley 22 on a shaft passing through a bearing sleeve 29 supported by plates 26 pivoted to a U-bracket 27 so that the plates may be rocked to adjust the tension of the belt. The rear wheel 9 rotates on an horizontal bearing sleeve secured to the lower end of a vertical rod 31 angularly and vertically adjustable in a U- bracket 33 that is laterally adjustable on a plate 35 extending transversely of the machine frame. The guiding handles 18 have adjustably secured thereto depending hangers 44 that pass through holes in a plate 40 secured to the bracket 33 : washers 48 and cushioning springs 45 are threaded on these hangers, the arrangement being such that normally the springs are not in engagement with the bar 40 but should it be necessary to lift the rear wheel the handles may be swung upwards about their pivots 19 until the bar is engaged and the rear of the frame lifted. A swath plate 49 may be fitted at the outer end of the knife bar.
